Dual Xeon Platinum 8260 blade server

The Dell EMC PowerEdge M640 is a half-height blade server fitted with two Intel Xeon Platinum 8260 processors. Each CPU runs at 2.4 GHz base frequency with a 3.9 GHz turbo boost and provides 24 cores. The system is aimed at virtualization, private cloud and high-performance computing workloads that demand dense compute resources.

Memory and storage controller limits

Sixteen DDR4 slots support up to 1.5 TB of registered ECC memory using 2933 MHz modules. The integrated PERC S140 controller handles SATA and NVMe drives with RAID 0, 1, 5 and 10 levels. Only two 2.5-inch drive bays are available, restricting local storage capacity compared with full-height alternatives.

Blade networking and management

A Broadcom 57810S-K daughter card supplies dual 10 Gb Ethernet ports for high-throughput east-west traffic inside the chassis. iDRAC9 Enterprise enables comprehensive remote management and automation without an operating system. The blade requires a compatible PowerEdge MX or M1000e enclosure and ships without front bezel or ready rails.

Questions about this item

Should I choose the 16GB DDR4 2933MHz configuration or add modules up to the 1.5TB maximum?

Start with 16GB DDR4 2933MHz ECC for light workloads; populate up to 16 slots to reach 1.5TB when virtualization density or in-memory databases demand it.

What does the 2.4GHz base and 3.9GHz turbo on the Xeon 8260 mean for actual throughput?

Two Xeon 8260 24-core CPUs run at 2.4GHz base and boost to 3.9GHz turbo, delivering 56 total cores for parallel workloads like virtualization and HPC.

How does the Broadcom 57810S-K 10Gb dual-port card limit real-world networking?

The 57810S-K provides two 10Gb Ethernet ports per blade, capping throughput at 10Gb per port for east-west traffic inside the MX or M1000e chassis.
